Keywords: 
	HST Observations

Description:
	This Dataset contains all HST observations taken as part of the AGEL survey. 
	The HST data consists of observations taken as part of three programs: 
		SNAP program 16773  ---  See https://doi.org/10.17909/aw94-d960
		SNAP program 15867  ---  See https://doi.org/10.17909/kpvc-r906
		GAP program 17307 (ongoing as of Jan. 2026) --- For data originally released as part of DR2 see https://doi.org/10.17909/dn2j-nz22. Observations that have been taken since the release of DR2 will be included in this Dataset.

Note: 
	- On Dataverse, target names which contain a '+' are saved with an underscore, e.g., 'AGEL001310+004004A' may have a directory name that displays as 'AGEL001310_004004A'.
	- All files are in FITS file format. Cutout images used for modeling are also provided in H5 format. 
	- The scripts used in the reduction process of this data are also available in the AGEL Dataverse at XXXXXXX
